I had some issues deploying NSX controllers in my lab and now I get a message in vCenter's "Networking and Security" section:

"2 Controller Deployment Failures"

How do I remove this message? There is no option to remove it in the GUI, and I cannot find anything related in the API guide (checking support notifications does not return anything).

Also, what could be a problem with deploying the controller on this host? The controller got deployed just fine on the second cluster node... The problematic cluster node also shows up in vCenter with a blue host icon when the other hosts have grey icons. I don't see anything different in this host's firewall setup.
